An interrogative sentence is one that asks a direct question and always ends in a question mark. In Indonesian language, interrogative sentences can be formed by: raising the intonation, adding a question tag, ‘bukan’ or ‘ya’; putting particle -kah on the object, subject or action; using interrogative pronouns or adverbs.
Adding a question tag, ‘bukan’ or ‘ya’ to the questions if we wish to confirm our questions;
- Kamu sudah makan, bukan?
- You have eaten, haven’t you? or You ate, didn’t you?
- Kamu sudah makan, ya?
- You have eaten, haven’t you? or You ate, didn’t you?
